HORSE-RAKE.

SPECIFICATION forming part of Letters Patent No. 245,685, dated August 16, 1881.

Application filed April so, leal. (No model.)

To all whom it may concern p Beitknown that LALEERTJAcoB WTLLsoN,

of the city of Toronto, in the county of York,

in the Province ot' Ontario, Canada, machinist,

have invented new and useful Improvements in HorseRakes, of which the following is a specification.

The object of the invention is to provide an easily-operated and effective friction-dump;

1o and it collsists in utilizing the movement ot' the main axle through the means ot' peculiarlyarranged friction-disks, operated as hereinat1` ter more particularly explailled.

Figure lis a perspective view of a horse-rake constructedin accordance with my illvelltion.

Fig. 2 is an enlarged perspective view, showing the arrangement of the dumping mechanism I employ. Figs. 2, 2b, 2c are detail views ot' the bearings ofthe toothbar. Fig. 3 is an enlarged detail, showing the arrangement ot' the friction-disks and lever for operating the same.

Fig. 4 is a detail of the bracket for supporting the inside ends ot' the maill axle alld atlachments conllected therewith. Fig. 5 represents details ofthe friction-disks. Fig. 6 is a detail of the triangular plates for operating simulta-V neously the two-levers used to adjust the friction-disks. Fig. 7 shows a side view and section of the friction-disks.

In the drawings like letters indicate corresponding parts in each ligure.

Aare the ground-wheels, keyed or otherwise secured to the axle B. This axle is divided in the center, the inner ends being supported in suitablejournals in the bracket O. This bracket is bolted to the cross-heanl D, upon the opposite side of which is pivoted the tooth-har E.

Fis a two-faced friction-disk jonrnaled on the ends of the axle B, and provided with an arm, G, having three holes, l, 2, and 3, in its end, as will be seen in Fig. 5.

H is a bracket bolted to the tooth-bar and to the pressure-bar I, which it assists in supporting.

4 5 J is a bar forming aconnection between the bracket H and the arm G. f When the pin j, connecting the bar J to the arm G, is passed through the hole marked 2 when the rake-teeth are down, the pins or pivots 7c and j both lie 5o in a straight line with the axle, thereby forming a rigid togglejoint, which, till brcken,will hold the rake-teeth down, preventing the rake being dumped bythe strain caused by raking heavy grain.

K are two friction-disks placed on the axle B, one on each side of the friction-disk F, the axle B passing thron gh all three friction-disks, as sllown. In order to secure the friction-disks K to the axle B so that they will constanlly revolve therewith, but lnay at. the same time be adjusted endwise, I pass a pill throllgh the sleeve of eacll disk K alld through the axle which supports it, lnaking a slot eitller in the sleeve of the disk or in the axle, as will be clearly seen on reference to Fig. 7.

L L are two levers, the end -of each being pivoted upon a pill ill the bracket O, extending from there to a pin near the cross-bar M.

b is a friction-roller journaled on the levers L opposite to the friction-disks K. By drawing these two levers L together the frictionrollers B, acting against the friction-disks K. force these latter disks against the two-faced disks F, which action, assuming the axle B is revolving, imparts a rolling movelnent to the disk F, alld through it to the tooth-bar E, as described, thereby dulnpin g the rake as desired.

A bracket, N, is bolted to the cross-bar M, with projecting lugs d, which constitute supports for the triangular plates O. One angle of each of these plates rests on the lugs d, the lower angle being provided with a slot, through which the bolt e passes, to connect the two plates to the crank P, which is keyed or otherwise fastened to the bar Q, having afootlever, Q', on it, as shown. The levers L hook into holesffin the upper angles of the plates O. Tllese plates, owing to the connection described, are caused by a movement of the l'oot lever O to rock upon their supporting-lugs d, 9o causing both levers Lto move together simul taneously, and in this way bring the two friction-disks K against the central friction-disk,

F, and in this manner impart the rollingmovement required to dump the rake, as described. In order to allow the rake to be dumped by hand when the bar J is secured to the arm G -by the pill j passing through the middle hole as is clearly shown in Fig. 2; and, furthermore, I provide a hand-lever, T, which is pivoted on a bracket on the crossbar M, close to the footleverR, but acting independently, except when drawn toward the driver, when it will come in contact with the end r of this foot-lever, when, through the movement of this foot-lever,which is connected, as shown, to the tooth-bar, the rake is dumped as desired.

In order to prevent the tooth-bar from sagging under the weight of the rake-teeth it carries, I provide a central bearing or bearings, E', bolted tothe cross-bar D, and so constructed that it p'erniitsthe square tooth-bar to roll Within it. In explanation of this bearing I show it in detail, Figs. 2f, 2c representing a cross-section of the cross-bar D and tooth-bar E at the pointwhere the bracket E is located. Fig. 2" represents the bearing-ring E2, which is made the shape shown, so thatits inside will gripe the square tooth-bar E, while its outside presents a smooth circular surface to t and revolve Within the bracket E.

What I claim as my invention isl. ln a horse-rake in which each groundwheel is secured to an axle Working independently of the other, but whose centers are on the same line, a two-faced friction-disk journaled on the ends ot' the two axles and suitably connected to the rake-bar, in combination with two friction-disks, one on either side of the two-faced disk, and each secured to its respective axle so that they revolve therewith, but may at the saine time be adjusted endwise, so as to come in contact with the two-faced disk between them, for the purpose of imparting a rolling movement thereto, substantially as and for the purpose specified.

2. In a horse-rakein which the ground-wheels revolve with their axle, africtiQn-diskjournaled on the said axle and caused to roll therewith by an adjustable friction-connection, and an arm extending from the friction-disk, in combination with a bar or link forming a toggle-joint between the said disk and a bracket on the tooth-bar.

3. In a horse-rake in which each ground- Wheel is secured to an axle workingindependently of the other, but form in connection a support for a two-faced friction-disk connected to the tooth-bar, and on either side of which is situated an adjustable friction-disk, a'lever pivoted behind each disk and provided with a friction-roller to prevent the pressure of the lever impeding the rotary movement of the disks when pressing them against the two-faced disk between them, in combination with two rocking plates, one for each lever, and connected together by a bolt passing through oblong holes in the plates, and connecting them to a crank so arranged that its movement will rock both plates simultaneously, thereby moving the levers either toward or from the adjustable friction-disks, for the. purpose of bringing them against the twofaced disk between them or releasing them therefrom, as required.

4. In a horse-rake having a stationary crossbar with brackets at either end to carry the rolling` tooth-bar, the combination ot' a ceutrally-located bracket or brackets, E', provided with a bearing-ring, E2, substantially as and for the purpose speciiied.
